Grove - Line Finder v1.1

Description of product


Most of automated robotic projects start from a line-following robot, Grove - Line finder v1.1 is designed to achieve this task easily and quickly. Those eye-like sensors on the board are actually IR emitting LED and sensitive phototransistor. When the phototransistor detects the reflected infrared light from the IR emitting LED, it will output a digital signal, which changes from HIGH to LOW.
